COMMUNICATION IN PLACES WITHOUT COVERAGE

IP voice gateway for radio networks

PVG is a PTT (Push-To-Talk) IP voice gateway application intended primarily for the dissemination of voice traffic of the *PEGAS network, but also for trunk and tactical radio networks of other manufacturers via the IP data protocol. The system enables the connection of voice communication between the radio network and the network of data services (WIFI, GSM). Radio stations in direct mode can also be used as radio network resources. This system finds application in places with insufficient radio network coverage, where it connects users using an application on mobile phones with users using radio stations in places with network coverage.

The user application for Android and iOS platforms – PVG Client can be integrated into the REDBAC service performance support application or 3rd party applications. The server part of the solution – PVG Server can be integrated into the ILS system to support central authorization management – user authentication, central management of voice groups (“talkgroups”) and other functionalities.

The client application enables communication in the team via mobile platforms – smartphones/tablets and has the option of keying with a wireless Bluetooth button for concealed carry.
